Keep in mind that Tomino is the only head writer for G-Reco.... Turn A had a number of writers helping him, including the same person who helped write King Gainer... He usually does a pretty good job directing, but some of his major faults appear when he himself is the only lead writer.
If anything, there wasn't another writer to help control some of Tomino's strange impulses... Wings of Rean ended up like that...
Let's not forget RING OF GUNDAM either... it was a CG short that was written by Tomino... but it didn't make any sense in the end...
